Aside from the fact that you've become my favourite my favourite Blender tutor since I started watching (right up there with the likes of Grant Abbitt etc), you're doing something that very few others are doing out there. You're not just showing off the "Oh, here's my cool 40k design, go download them", you're actually showing people how to create their own. This, in my opinion, is far more valuable and worthwhile. (Added bonus, less chance of /them/ coming after you.) Thank you and keep up the great work.
Wow, being mentioned in the same sentence as Grant is Hugh praise indeed, thankyou so much! To be honest showing people how to do it themselves is so much more rewarding than doing it and seeing sales (I think that's the teacher mentality in me, it's the same reason I quit my former job to become a teacher despite the notable pay drop). Thanks again 😁👍🏻
If you want to APPLY the geometry node modifier at the end, read this first! You can not apply geometry nodes on curves. So always use meshes and dont convert them to curves! You can then use the "mesh to curve" node inside the geometry node to get the curve. At the end you need to use the "Realize instances" node just before the geometry output. That way you will be able to apply the geometry node modifier. I just had a real pain because of that, which did cost me many hours.
Thank you for your awesome video! It really helps a lot in my modelling and understanding of these geometry nodes. The details are also explained very well so that beginner like me can easily follow. Thank you again for your effort to share these with us!
Thanks mate. I was really struggling with this, for some reason I can't get this to work with "Curves to Points" node used by other youtubers, the rotation is always messed up. This video really saved me!
Cool Video. Very nice trick. One extra Tip. If you use the curve it in combination with a Shrinkwrap Modifier (what is super common with curves attached to a mesh) make shure you activate the "Apply on Spline" Function in the Shrinkwrap! Otherwise it will override the information for the curve tangent and the direction align effect will not happen. I faced that phenomenon a few minutes ago and was confused. So I tell you that hopefully you don't have to! 😁
Ooh fun, an elevated approach using Geo Nodes! I discovered your channel from the previous method using arrayed instances. Thanks for sharing the geo nodes workflow! Cheers, Blake
Cheers Blake. Glad you're liking the combination of GeoNodes with other elements. They seem to be too often looked at in isolation so it's nice to bridge the gap.
Oh is there? Have you got the name for it? I mean this is about 5mins of when when not explaining so that's going to have to be VERY good to be worth a high cost (also when doing it yourself you can add cool things like a twist).
Hmm... that's a good question. Animation isn't something I really do so I'm not sure to be honest. I guess you'd need to change the position of each of the subdivisions. Or have more subdivisions and have the teeth flow from one to the next using something like a modulo math node. But I can't say I've tried it.
Love this! Made it super simple! 🙌 Question: is there a way to offset a rotation along the curve? (I'm using playing cards and want them to twist along my curve)
So you'll need to manipulate the rotation. I would probably combine in something like the index so that each one a long is a bit more rotated in the axis of your choosing.
Its because this is using instancing in the back ground. Add in a node "realise instances" after the instancing and it should work. I should have put that in the video.
Great video, as always. I am watching all of them! Question: How do I apply the GeometryNodes modifier? I have to convert the curve into mesh, but then the modifier disappears before I can apply it. Thanks in advance
Thanks so much! It should be in the modifier stack to the right as a normal modifier. You just need to be clicked on the object to then apply it. Does that help?
I could add some 3d printing elements. But basically yes. The only thing is if the instances overlap it's best to combine those first and there is a great trick for that (once again thanks to Geometry Nodes). You can check that out here: th-cam.com/video/fe8FM5jHOQk/w-d-xo.html
That one is really helpful. It works really good for tank tracks as well! I got a slight problem, however. The legth I entered in "Resample Curve" seems to differ along the track. Towards the back and front end of the track, where the track curves around sprocket- and idler wheel, the distance between links becomes bigger. Both, curve and track link have correctly applied scales. Any idea what the reason for this problem could be? At first glance the difference may go unnoticed, but at a closer look it becomes obvious, so I really would like to fix that.
Edit: I thought I had the solution: I got my origin at level with the inner surface of the track. so that there is no overlapping with the wheels. Instead the origin should have been in the axis of the connectors of the track. The wheel-overlap can easily be handled with the transform operator. But that causes the same issue. As can easily be seen when exaggerating the translation (offset) from the curve: In tight parts of the curve the elemets get stretched much further away from each other than in flat parts.
@Hugos Hobbies That's really interesting and something I hadn't noticed. I'm assuming this is a curve that is circular (as in it doesn't have an end, its continuous)? If that's the case does this incorrect distance happen once or multiple times? Of it's once I would assume its because its where the "ends" of the circle join up and the circumference isn't exactly divisible by the length your inputting in the resample. It will have to make up the remainder amount somewhere. I can't say that for sure but that would be my guess. I might need to have a play around.
@@ArtisansofVaul I figured it out. Essentially, the Transform function works here like an "extrude individually along normals". The sharper the angle between two arrayed objects, the larger the gap between them becomes. Therefore, using Transform is not an option here, and the origin of the track link needs to be centered where the track links are longest. However, as I mentioned earlier, this would result in the track intersecting with the wheels. The simple solution was to slightly increase the size of the curve. Initially, it was tangent to the wheels, but now there's an even gap between the curve and the wheels, just as big as the distance from the track link's origin to its face pointing inward along the curve.
To be honest I don't really animate as I model for 3D printing so there are probably better channels out there for that sort of animation. I would suggest searching for how to animate something like tank tracks as they would use the same technique.
You'd need to extract a curve but it should do yes. You might prefer this technique thought for a wavey/curved surface, it's what I would use- Placing rivets with the Raycast Node: th-cam.com/video/wFaODMBxZD4/w-d-xo.html
It would be a very tight fit, I agree. But that is very similar to most GW designs. I assume that the teeth actually oscillate in most "chain" weapons otherwise most would be impossible to fit them, or they just ignore it like the tracks on a Leman Russ not having room for the support wheels of the tracks, or 10 (now 12) marines being able to fit in a Rhino.
🤣 It's a hell of an improvement to what you used to have to do to get a non-deformed object along a curve. Standard array along a curve is easy, it's when you want them to rotate that it's a little bit more work. I still don't think it's too much tome/effort.

Im almost certain that would be possible. I would imagine you would link the scaling to the spline length.
